Patent DE-1921530-A1 (DE)
Title: Controlling the output of a power station - with a boiling water reactor in a single
Inventor: ERNST HELMUT
IPC: F22B35/00
Filed: 1969-04-26
Abstract: A circulation control varies the number of revolutions of the pumps in the circulation cycle as a function of the difference between the required and the actual output. Factors interfering with the required output are eliminated by a device acting directly into the reactor steam chamber. Specifically, a portion of the feed water is passed via a control valve, a pipe and a distributer system into a steam-holding chamber above the reactor nucleus as a function of the required output.

Title: Alcohol-reduced beer prodn. - having a good taste in a two-stage process
Inventor: KLEBER WILLY DR
IPC: C12H1/00
Filed: 1973-11-10
Abstract: A beer of reduced alcohol content is made in two stages (a) by producing a hop-free beer conventionally(recovering the wort and brewing 75%) and (b) adding hops to the remaining 25% so as to produce quadruple the bitterness ordinarily obtd. After brewing, the alcohol is removed from (a) and replaced by an equivalent amt. of pure water when it is added to (b) in amts. of e.g. 3:1 v/v. Previous methods have left an unpleasant taste due to side-reactions occurring during the distillation of the alcohol or still taste of brewed wort if brewing was stopped early to reduce the alcohol content (in which case the beer also has a high content of brewable sugar and thus also a high calory content). The alcohol may be removed from (a) by conventional means (distillation under reduced pressure, when the CO2 has to be replaced or by osmosis) as an alcohol-water mixt.
